[SOLVED] - Strange problem with POST data

I tested on a new debian 10.5, and the post data not work....
I think that my problem still in my "approach" to CI4. 
I explain you what i do:
In the new debian box install apache2, php, mysql (mariadb). 
I make the configuration for apache2 (document root, ecc)
In the directory configurated, run the command " composer create-project codeigniter4/appstarter"
After this command, rename env to.env and I change Cienvironment to development
I set the base_url "http://www.mysite.com" and remove "index.php"
I set the ht access and the site works fine... 
Is it correct?
